Research
I investigate how organisms respond to global environmental change. My work connects ecotoxicology, ecophysiology, and evolutionary ecology, using fish, insects, and other organisms to understand responses to multiple stressors.
Life under environmental pressure
In the wild, organisms encounter many different stressors that can interact in ways that lead to unexpected effects. Pollution, for instance, can occur alongside temperature changes and pathogens. I study how these pressures interact, and how their effects propagate across levels of biological organization from molecular and cellular levels to the individual level, focusing on behavior, growth and survival.
My approaches combine field observations, reciprocal transplants, and controlled experiments. Together, they help disentangle associations in natural environments from causal responses to specific stressors.
Why individuals and populations respond differently
Individuals and populations can respond differently to the same stressor. I am interested in how this variation reflects plasticity, exposure history, and local adaptation, and what it means for population persistence.
More specifically, I investigated how responses to metal contamination and immune challenges vary among wild freshwater fish populations, including a study of their gut microbiota, physiological and behavioral responses, and variation in movement and thermal performance among parasitic micro-wasp populations. The work on animal movement also inspired the MoveR package.
Pollinator health in a changing environment
Since January 2025, I have been a research scientist in the Bees & Environment unit at INRAE in Avignon. My current work investigates how contaminants and other environmental stressors affect bee health, with a particular interest in wild bees.
I also co-coordinate the Pesticides & Pollinators Group within the POLLINECO network.
Research in practice
- Ecotoxicology: laboratory and field experiments, including reciprocal transplants to understand effect of contaminants on organisms.
- Integrative biology: connecting physiology, behaviour, microbiota and organism performance.
- Quantitative methods: reproducible analyses and tools for animal video-tracking data.
- Open science: sharing data, code and practical resources to support reliable research.
